crab misses the point, only because he thinks the FLIR is meant to replace instruments. Not so. In fact, that is where this thread went south, IMHO.
The use of a FLIR or Low Light Level TV image to aid the crew in situational awareness is the issue. No doubt, instruments keep you on track, but too many accidents result from the crew losing the "big picture"
Too many CFIT accidents are preventable, using technology that is cheap enough and reliable enough to make a big difference. The FLIR doesn't have to see thru clouds and rain to save a great percentage of helo drivers, according to accident stats (although one wishes for theat extra capability!)
About 25 years ago I started Sikorsky on the path of developing what became the Comanche helmet. The whims of the Army stopped that system from hitting the street, but it will come, and when it does, it will revolutionize our flight capability and safety.
